Now's your chance Prosper. I don't see the issue here. It's a smart move. The dev's get a bunch of assets and they can pick the best ones to put in the game, the boys and girls that submit their work get the opportunity to show their competence and if they make it in the game it will be a breaktrough for them. I was sceptical when they said they where using the unity store to to purchase pre made assets but now i think its a great idea as it gives the community a chance to improve the game. It's a brilliant move and i applaud you.
